Just ran 3D Mark. I have an ASUS P8Z68-V motherboard (with latest BIOS update), i5 2500k with a stock cooler running at 4.4GHz max (done automatically by motherboard out of the box), 8GB DDR3 1866 Ram, and a NVIDIA GeForce GTX 560Ti.
I used CPUID HWMonitor to see how the temperatures do during the benchmark and here were the max temps. I have no idea if they are too hot, they seem a little hot to me but I figure you guys know more than I do:

They are on the warm side, but anything under 80c is usually considered ok. And considering your clocked at 4.4 I think your ok.
I'm more concerned about the SYSTIN, AUXTIN and CPUTIN temperatures. Are those not as serious as CPU core temps ?
